How to read this datasheet
Dyness 20kWh High Voltage Battery with BDU is listed with 10 published specifications from Dyness, including cooling method of Natural Cooling, applications of Residential, Commercial & Industrial Energy Storage, battery chemistry of Lithium Iron Phosphate (LiFePO₄ / LFP) and battery distribution unit of Included (BDU). Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.
For a battery, the figures that matter most are nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh), usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%, system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack and continuous charge and discharge current, which limits how much power you can draw from the pack. Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.
What to check before ordering
The checks below apply to any battery. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.
- Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.
- Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.
- Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.
- Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.
Common mistakes
- Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.
- Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.
- Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
Price and availability in Pakistan
No price is published for Dyness 20kWh High Voltage Battery with BDU in Pakistan at the moment. Pricing on solar equipment moves with supply and exchange rates, and some distributors quote only on request — the specifications above are still directly comparable against alternatives that do list a price.
SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in Pakistan: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Dyness locally before ordering.
Dyness 20kWh High Voltage Battery with BDU — frequently asked questions
What are the specifications of Dyness 20kWh High Voltage Battery with BDU?
We hold 10 published specifications for this battery, including cooling method Natural Cooling, applications Residential, Commercial & Industrial Energy Storage, battery chemistry Lithium Iron Phosphate (LiFePO₄ / LFP), battery distribution unit Included (BDU) and battery type High Voltage Energy Storage Battery. The full table is on this page, listed under model DYNS-11.
Who makes Dyness 20kWh High Voltage Battery with BDU?
Dyness 20kWh High Voltage Battery with BDU is a Dyness product, listed under batteries with model reference DYNS-11. The Dyness brand page lists the rest of its range so you can compare across the catalogue.
Is Dyness 20kWh High Voltage Battery with BDU right for my system?
That depends on what it has to connect to. For a battery, check cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4, round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid and communication protocol (CAN or RS485) for talking to the inverter against the rest of your equipment before price enters the decision. Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.
Where can I buy Dyness 20kWh High Voltage Battery with BDU in Pakistan?
SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in Pakistan — buying in-channel is what keeps the manufacturer's warranty valid.
